SIR – I don’t know why the BBC spent so much licence-payers’ money making a documentary about international transport drivers of a furniture and houseware company recruited from Eastern Europe, as any transport driver here could have told them that 20 years ago.

Companies have been using this method of worker exploitation for many years.

I used to often pass one depot in Germany, just past Luxembourg, whose trucks suddenly sported Bulgarian number plates.

They are based in one EU country but register trucks in another, often with lower VED and minimum wage rates, with drivers usually only paid when running loaded, so if waiting for another load get paid nothing; they just camp out in the country where they last unloaded.

This has been of concern in the UK for years, with many foreign trucks dominating motorway service areas or industrial estate roads where lack of toilets etc causes other problems.

Most long-haul drivers, myself included when working, carry a gas cooker, food and water etc, as foreign ones on low wages can’t afford to buy meals out, even UK ones, as it doesn’t go far at motorway prices.

Maybe Brexit might help solve this problem?
